The EL7154 three-state pin driver is particularly well suited

for ATE and level shifting applications. The 4A peak drive

capability, makes the EL7154 an excellent choice when

driving high speed capacitive lines.

The P-Channel MOSFET is completely isolated from the

power supply, providing a high degree of flexibility. Pin (7)

can be grounded, and the output can be taken from pin (8)

when a “source follower” output is desired. The N-Channel

MOSFET has an isolated drain, but shares a common bus

with pre-drivers and level shifter circuits. This is necessary to

ensure that the N-Channel device can turn off effectively

when VL goes below GND. In some power-FET and IGBT

applications, negative drive is desirable to insure effective

turn-off. The EL7154 can be used in these applications by

returning VL to a moderate negative potential.
